Force Pairs PRACTICE QUIZIZZ

Newton's Third Law states

• Objects in motion stay in motion and objects at rest stay at rest

• Force is equal to mass times acceleration

• For each action there is an equal and opposite reaction

Based on Newton’s 3rd law, the force pairs always act on _______.

• different objects

• the same object

• objects in motion

Whenever an object exerts a force on another object, the second object exerts a force of the same magnitude (size), but in the opposite direction to that of the first object.

• Always True

• Never True

• Sometime True

Force always comes in

• waves

• pairs

• triplets
